SPECIFICATION forming part of Letters Patent No. 726,780, dated April 28, 1903.

Application filed June 4, 1902. Serial No. 110,246- (No model.)

To ctZZ whom it may concern:

Be it known that 1, WILLIAM EVERETT SPROUL, a citizen of the United States, residing at Guatemala city, Guatemala, have invented certain new and useful Improvements in Pile-Drivers, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention'is to provide an improved pile-driver by means ofwhich piles may be driven at an angle to a vertical line and also below the base of the pile-driver, a further object being to provide a piledriver which maybe easily and conveniently moved laterally, forwardly, and backwardly, or turned, as on a pivot, afurther object being to provide a pile-driver in which the hammer-guide may be conveniently moved transversely of the base of the apparatus and swung laterally, so as to facilitate the driving of piles at an angle, a further object being to provide a pile-driver having an upright frame portion which supports the hammer-guide and which is provided with a laterally-movable carriage with which the hammer-guide is connected, the base-frame of the apparatus being also provided with a forwardly and backwardly moving member with which the lower end of the hammer-guide is connected, so as to move laterally thereon; and with these and other objects in view the invention consists in a pile-driver constructed as hereinafter described and claimed.

Figs. 34 and 35 are opposite views of a detail of the construction shown in Figs. 20 to 32, inclusive; Fig. 36, a top plan View of a lifting-block forming a part of the construction shown in Figs. 29 to 32, inclusive; Fig. 37, a side view of a part of my improved pile-driving apparatus and showingasupport on which the same may be moved; Fig. 38, a plan view of the support.

In the construction of my improved piledriver, reference being made to Figs. 1 to 5, inclusive, I provide a base-frame, which comprises two horizontal and parallel side members a, preferably composed of two separate parts a which are separated at intervals by blocks a as clearly shown in Fig. 5, and said side members are connected at the ends by transverse end members a or in any desired manner and also intermediate of the end by transverse members a two of which are shown, and between the intermediate members a are diagonally-arranged members a which intersect each other at the center of said base-frame, as shown at a, and the diagonally-arranged members a are also preferably composed of separate parallel parts separated by blocks a the same as the separate parts of the side members a.

The separate side members a are preferably provided near their front ends with bands b, and mounted in the front ends of said side members and between the separate parts (1 thereof are slides 12 connected at their front ends by a cross-head b movable back and forth, as hereinafterdescribed, and which forms a support or connection for the lower end or bottom of the vertically-arranged hammer guide, as hereinafter described.

The separate side members a of the baseframe are also provided at intervals with lifting devices 0, three of which are shown, and the intermediate transverse members a are provided with similar lifting devices, two of which are shown, and the diagonal base-frame members a are also provided with similar lifting devices, four of which are shown, two in each of said members, and all of these lifting devices are designated a whole by the reference-letter c, and said lifting devices are of the construction shown in Figs. 25 and 29 to 36, inclusive. The bottom of said side members ct of the base-frame is preferably provided with a plate 2, and in constructing the lifting devices 0 I place between the separate parts a of the side members a of the,

shaped bands 0 are passed over the top ends of said blocks 0 and adjacent the cross-heads at the top thereof and are clamped in position by a screw or screws 0 operating in connection with the parts a and between the yokes c are blocks a which are held in place by plates o the upper ends of which overlap the opposite blocks 0 and the lower ends of which pass beneath the separate parts or bars a as clearly shown in Fig. 31, and the upper ends of said yoke-shaped plates are connected with the block 0 by screws 0 or in any desired manner.

Placed between and supported by the upper ends of the blocks 0 is a nut 0 provided with a groove in which fits a projection or projections c", formed on said blocks and by which said nut is securely held in place, and passing downwardly through the nut o is a screw d, provided with a head 61*, having radial holes (1 adapted to receive a turning bar or lever, as will be readily understood.

Between the blocks a and the parts a are placed verticallymovable blocks d (shown in section in Fig. 30,) and these blocks are separated longitudinally of the base-frame by an intermediate block (F, the ends of which are countersunk in the blocks (1, and held between the upper ends of the blocks (1 is an angle-plate d, the ends of which are countersunk in the block d and the central portion of which projects above the upper ends of the blocks d and the lower end of the screw (Z passes through the central portion of the angle-plate d", as clearlyshown in Fig. 30, and is connected therewith so as to freely turn therein, as shown at d. The blocks (1 and (Z are connected by bolts CF, and between the lower ends of the blocks d is mounted a roller cl. As thus constructedit will be seen that the blocks 0 which support the nuts c are supported by the bars a of the side members of the base-frame, and by turning the screw (Z the supports of the roller (Z may be raised or lowered, according to the direction in which the screw dis turned, and said roller may be projected below the bottom of the base-frame or raised above the same, as will be readily understood.

As hereinbefore stated, all the lifting devices care of the same construction, and those lifting devices in the parallel side members a of the base-frame may be operated so as to raise said frame and the upper structure of the pile-driver above the support or supports thereof, and the entire apparatus may be moved laterally or sidewise in either direction, as will be readily understood, the rollers (1 being arranged longitudinally of the baseframe. In the lifting devices a, which are placed in the intermediate cross-heads M, the rollers d are arranged transversely of the base-frame, and if it is desired to move the pile-driver longitudinally or forwardly or backwardly these lifting devices are manipulated so as to depress the rollers at below the bottom of the base-frame, in which position ofthe parts the pile-driver may be moved longitudinally or forwardly or backwardly, as will be readily understood. In the diagonally-arranged members a of the base-frame the rollers d are arranged longitudinally of said members, and by reason of the diagonal arrangement of said members when the rollers d in said lifting devices are depressed the pile-driver may be tnrned 'on a central pivot and swung in a complete circle, the rollers d in the lifting devices in said diagonal members supporting the entire apparatus and forming hearings to permit of the turning of the pile-driver, as described, and in this operation a suitable pivot-pin is passed through a central opening at a and into the support of the pile-driver, or said pile-driver may be turned in a circle without said central pivot-pin.

The cross-head b which is connected with the slides 12 at the front end of the baseframe, is provided with a rope or cable b which is connected therewith in-any-desired manner and which passes forwardly and may be connected with a Windlass, engine, or other operating'device, and secured to the inner ends of the slides 13 at (9 in any desired manner are other ropes or cables 1), which are passed around pulleys 19 secured to the front end of the base of the main frame and which are also passed backwardly and may be connected with a. Windlass, engine, or any other operatingdevice, and by means of the ropes or cables I) and b the cross-head b may be forced outwardly or forwardly anddrawn backwardly whenever. desired. Connected with the side members a of the base-frame at a predetermined point and preferably just forward of the forward inter mediate transverse member M, as shown at 7 in Fig. 3, are upwardly and forwardly directed bars or supports b with the. upper ends of which is connected a transverse sup porte and with the opposite ends of which are connected bars or stay-rods 6 which ex-' tend baokwardly and which preferably cross each other at e and are connectedwith the. rear end of the base-frame at e, and the trans-' the outer sides of the 'platese at the top thereof, are bars'e the bottoms of which are provided adjacent to the plates 6' with a longitudinal groove 6 a Mounted onthe support 6 is a sliding carriagef, (shown in Figs. 1 to '5, inclusive, and also in Fig. 11, and a cross-section of which is shown in Fig. 12 and details thereofbeing shown in Figs. 13 and leg) and this carriage is composed-of side bars f anda central bar f ,-which rests on the central member e! of the support e and the bottom portion of which fits between the tops of the-side plates 6 of the support 6, and said carriage is pr0- vided with side hangers f having inwardly and upwardly directed brackets f and mounted in the lower ends of said hangers are rollers fflwhich bear on the bottoms of said bars or bearings e of the support e, asclearly shown in Fig.12. side membersf of 'thecarriagefand connected therewith in any desired manner are bearings in whichis mounted a transverse shaft f which passes through a centrallyarranged block g, to which is secured a top block g and the blocks g and 9 form abeare.

ing forthe shaft 9 the ends of which are extended, as shown at 9 in Fig. 27, and provided with arms or brackets g which are secured to and support the hammer-guide h,- and by reason of this construction it will be seen that the lower end of the hammer-guide may be swung laterally or backwardly and forwardly by reason of its connection tothe carriage f. Connected with the opposite endsof the carriage f are ropes or cables g ,-which pass over pulleys g in the opposite ends of the support 6, and said ropes or cables are passed downwardly and backwardly around suitable pulleys or other devices 9*, connect ed withthe upright portion of the frame ofthe pile-driver formed by the upwardly andforwardly directed bars 5 and. said ropes or cables arepassed downwardly and forwardly and in practice are connected with-a windlass or engine, and by .the proper manipulation thereof the carriage f may be moved ineither'direction on the support 6, as will b readily understood.

The hammer-guide his composed of two Mounted on the opposite separate vertically-arranged side members,

each of which is composed of two parallel parts-h separated'by blocks h this construction beingsimilar to the construction ofthe side members ofthe base-frame,-and'-the separate vertically-arrangedmembers 7L2 are preferably connected at their forward sidesbytransverse bars hfl-andthe separate side members of'the hammer-guide are also provided at the upper ends thereof 1 with front plates h which are secured thereto, and

mounted in the top of thehammer-guide isa pulley h, around which passes a rope',--cord,- or cable h",which is connected with the ham- I20 mer h and which passes forwardlyand downwardly around the-pulley it, connected with the upright'portion of the frameofthe-piledriver, from which-point it is carried 'for-Q wardly and passes around-another pulley 9,

connected with the base-frame, and in prac-' tice this cord,-rope, or cable is connected with an engine and operated intheusual manner. rear side with a support 8",which supports two The ca-rriagef-"is provided at its pulleys 7", which are arranged closely adja-" cent, and-the hammer rope, cord, or='cable"h ispassed betweenthese pulleys, and by reason of thisconstructionthe hammer may a1- ways be properly operated regardless of the position of the carriage fon the support e. The lower end of the hammer-guide h is connected with the cross-head 11 which is connected with the slides b in the front end of the base-frame, as hereinbefore described. This connection is made in the following manner, details thereof being shown in Figs. 17 to 20, inclusive: The cross-head b is provided, as shown in Fig. 5, with longitudinallyarranged holes 1', adapted to receive pins 2' as shown in Fig. 17, and ayoke-shaped bracket 1' is connected with the cross-head b by means of the pin i The lower end of the hammer-guide h or one of the side members thereof is provided with reinforcing vertically arranged members 1 consisting of plates or bars bolted thereto, as shown at i this construction being clearly shown in Figs. 21 to 24, inclusive, and secured to the inner or adjacent sides of the plates or bars t are vertically-arranged strips or keepers i (see Figs. 18, 21, and 23,) between which and the bars 2' is placed a vertically-arranged and slidable key-piece V, which is of the form in cross-section shown in Figs. 18, 19, and 22, and connected with the bracket 7 at 2' and so as to turn therein is a pivot device It, which passes into a slot k in the key-piece 2' and which is pivoted thereto by a pivot-pin at 70 and a strengthening-band k is secured to the key-piece i where the pivot-piece 70 connects therewith, and by means of this construction the bottom end of the hammerguide may he moved forwardly and backwardly with the cross-head 19 as will be readily understood.

That part of the hammer-guide shown in Figs. 21 and 23 is the lower end of the lefthand leg or side of said hammer-guide, these views being inside perspective views of said side or leg of the hammer-guide, and in the construction of these parts, as hereinbefore described, I connect with the separate parts or side portions 72.2 of said leg bands m, three of which are shown, and these bands extend transversely across the front of the said leg or side of the hammer-guide and backwardly transversely of the inner side thereof and transversely across the rear face of the inner side member 71 thereof and then backwardly across the inner face of the corresponding piece i as clearly indicated in dotted lines in Fig. 21, and said bands are countersunk in the parts 71 of the hammer-guide leg or side and also in the inner face of the part 71 as indicated in dotted lines in Fig. 18, and these bands are held in place by the bolts t, which also pass through the cross-bars m which connect the separate legs or sides of the hammer-guide at the back thereof. The lower band m at the lower end of the side or member of the hammer-guide is not connected with a cross-bar m but this band may also be secured in place by bolts i if desired. I also provide means for extending the lower end of the hammer-guide when it is desired to drive piles below the level of the base-frame of the apparatus, and in Figs. 15 and 16 I have shown one form of construction for this pin pose and in Figs. 21 and 23 another construction designed for the same purpose. Each of the forms of this construction above referred to involves a vertically-arranged slide m mounted in the lower ends of the legs or sides of the hammer-guide and provided at the lower end with aband m and these slides may be raised and lowered in any desired manner or by any preferred means, and in Figs. 15 and 21 the said slides are shown in their lowered or partially-lowered position, and in Fig. 23 the said slide is shown in its raised position.

In the construction shown in Fig. 15 I employ a supplemental leg-piece m (shown in Fig. 16,) and the lower end m of which is so formed as to enter the band m at m and the upper end of said supplemental leg-piece is beveled or inclined at m and the inner part 71. of the separate side members or leg members of the hammer-guide are beveled at their lower ends, as shown at m, and the supplemental leg-piece m in practice is set into the space between the hand hi and the beveled surface m and is locked therein by a vertically-movable piece 72, mounted in the leg-piece 71 and provided with an angular upper end member 72 moving in the recess or chamber n in said leg-piece, and by means of the parts m and m the lower ends of the separate sides or leg members of the hammerguide may be extended downwardly, as will be readily understood, the extent of this extension depending on the length of the piece m.

In the form of construction shown in Fig. 21 I substitute for the supplemental piece 017. another part or member W, the lower end a of which enters the band 072 of the slide 771 and the upper end of which at n is adapted to enter beneath the lower band on at the lower end of the side or leg member 77. of the hammer-guide. Any suitable means may be employed, however, for securing the parts m or n in place, and various forms of construction may be employed for this purpose without departing from the scope of myinvention.

The separate sides or parts I) of the up right portion of the frame of the apparatus are provided with cross-braces 0, between which are diagonal braces 0 and at the top of the upright portion are diagonally-arranged braces 0 which connect with the horizontal support 6 of the hammer-guide carriage; but it will be apparent that the upright portion of the frame of my improved pile-driver may be made in any desired manner, as may also the base-frame, the only object in this connection being to provide a suitable base-frame with the slides 17 and the lifting devices 0'.

In Figs. 6, 7, 8, 9, and 10 I have shown my improved pile-driver mounted on supports 0 connected by cross-bars 0 and I have also shown piles A in the operation of being driven, and the supports 0 also represent piles previously driven and on which the piledriver is placed; but it will be understood that in the operation of .this apparatus when it is desired to move the pile-driver laterally or forwardly or backwardly or to turn the same it must be placed on a floor or support on which the rollers of the lifting devices 0 may operate. It willalso be observed that in Fig. 7 the lower end of the hammer-guide h is extended for the purpose of driving piles below the base-frameof the pile-driver, and a portion of the piles o in this figure are show as so driven.

In Figs. 9 and 10 I have also shown supplemental braces or tie-rods 0 which connect the front end ofthe base-frame with the central part of the upright portion of the frame of the apparatus; but these devices are not shown in Fig. 3 and may or may not be employed.

From the foregoing description it will be seen that the entire apparatus may be raised and moved forwardly or backwardly whenever desired, that it also may be raised and moved laterally in either direction whenever desired, and that it also may be raised and turned as on a pivot whenever desired. It will also be seen that the ham mer-guide is supported by a carriage which moves on a horizontal support and that said hammer-guide may be moved laterally in either directionwithout moving the framework of'the apparatus, and that by reason ofthe connection of the hammer-guide with the carriage the lower end of the hammer-guide maybe swunglaterally and forwardly and backwardly, the connection of the lower end of the hammer-guide with the base-frame of the apparatus being suchas to permit of this operation. It will also be seen that the lower end of the hammer-guide may be extended, so as to permit of the driving of piles below the base-frame of the apparatus, and this position of theparts is-shown in Fig. 7, the lower end of the hammer-guide being extended for the purpose specified.

In Fig. 6 I have shown-the lower end of the hammer-guide without the extension feature or the extension feature thereof being closed, and in Fig. 8 I have shown the lower-end of the hammer-guide swung to the left, so as to drive a pile at an angle to-thevortical center of the pile-driver.

In Fig. 9 I have shown the separate parts of the apparatus'in their normal position or in the position theyoccupy when driving ordinary piles, and in- Fig. 10 I h'avegiven a similar viewshowing thebottom of the hammer-guide drawn backwardly, so as to disconnect it from the end of the pile which is being driven, the piles in these figures being designated-by the'reference character A.

It frequently happens in driving a pile that it strikes a rock or obstruction andcannotbe driven farther, andin this event it becomes necessary to saw off a part thereof, and with my improvement the lower end of the hammer-guide may be swung backwardly and the pile may be sawed off, as will be readily unand capped by cross-beams P which are firmly secured to the piles P by means of spikesydogs, or'otherwise. On the crossbeams P I place stringers P which are so spaced as to be beneath the rollers d of the lifting devices 0, which are secured tothe I cross intermediate members a and which are arranged for forward or backward movement of the driver; but the side stringers a support the driver upon the stringers P when the driver is in use, the rollers only being used when it is desired to move the driver, such movement being accomplished by means of skidding.

When itis desired to move the driver transversely, the driver is raised by means of the lifting'devices a, just mentioned, and transverse beams l? are placed beneath the rollers d of the lifting devices 0, secured to the side stringers a, and these drivers being manipulated the driver rests uponthem and the.

transverse stringers P and may be moved transversely.

If it is desired to swing the driver, a platform P may be placed beneath the driver, and when the lifting devices 0 of the diagonally-arranged members a are manipulated and the driver rests upon these rollers and the platform P and when a pin'i's passed through a into the platform I the driver may be rotated about said pin.

Ifa wharf is being built which requires a permanent platform, the driver may be moved in any direction by manipulating the set of lifting devices which are arranged for the direction desired, the'othersets being elevated out of the way, and if no platform is built for permanent use and longitudinal movement being desired the temporary platform P and transverse beams P must be removed, andthe driver again rests upon the longitudinal stringers P i My improved'pile-driver is comparatively simple in constructionand operation-and also comparatively inexpensive, and my invention is-not limited to the details of the construcspirit of my invention or sacrificing its advantages.
